Rhiznphagus.'] Clavicornia. 205 



disc of thorax sometimes darker ; thorax longer than broad, widest in front, 

 very slightly contracted Ix'hind, with anterior angles very plainly marked, 

 "with coarse anil ditl'use punctuation ; club of antennai oval ; elytra de- 

 pressed, parallel to middle and thence gradually narrowed, with rather 

 "weak and comparatively finely punctured striaj ; the species may be easily 

 distinguished from li. depressas, which at first sight it much resembles, 

 by the much coarser punctuation of the thorax, and from H. jMrallrlocollis 

 and It. ferrugineus by its average smaller size, and the more finely and 

 less closely punctured stritc of elytra ; the thorax, moreover, is not quite 

 as closely punctured on disc as in these two species. L. 3 mm. 



Under bark, at sap, &c. ; not common; Chatham, Shecrness, Darenth, Miclileham, 

 Sliirkiy, Esher, Faruham, Parley, &e. ; Ipswich; St. Peter's, Kent (in decaying pota- 

 toes, one specimen, T. Wood); Hastings; Weymouth; New Forest; Portland; 

 Devon; Saltbrd Priors; Bewdley ; Sutton Park, Birmingham; Church Stretton ; 

 Piuldon Wood, Lcict stershire ; Sherwood Forest ; Scothind, rare, amongst old wood, 

 Solway district only ; Ireland, Galway (J. J. Walker). 



Zl> parallelocollis, Er. Larger on the average than the preceding, 

 and as a rule of a darker ferruginous colour, with the disc of thorax and 

 hinder half of elytra very often clouded witli blackish-brown ; head 

 nearly as broad as thorax ; thorax longer than broad, widest in front, 

 very slightly narrowed behind, coarsely punctured ; elytra depressed, 

 especially in the nuddle, with rather strong plainly punctured stria3 ; the 

 species most closely resembles R. ferruriinem, from which it may be 

 know^i by its more depressed form and larger head ; occasionally 

 specimens are found which are coloured almost like R. dispar ,- the latter 

 species, however, is less depressed and narrower, and has the thorax 

 evidently longer and less coarsely punctured. L. 3-4 mm. 



Under bark, at sap, iu fungi, &c. ; local ; Darenth Wood, Miekleham, Forest Hill, 

 Esher, Shirley, Chatham ; Regent's Park, in a tree infested by Cossus ; Dean Forest ; 

 Sherwood Forest ; the late Archdeacon Hey once found it in numbers iu a cemetery 

 near York in a fungus (Copris comatus) in company with Alomaria fimelarii ; 

 Northumberland and Durham district, not rare, on the walls and tombstones of grave- 

 yards ; Scotland, rare, Solway district. It has lately been recorded as abundant iu 

 France in coffins in grave-yards, buried at some depth below the ground. 



R. ferrug-ineus, Payk, Eather dark ferruginous^ iinicolorous ; head 

 small, considerably narrower than thorax ; thorax longer than broad, 

 scarcely narrowed behind, very strongly punctured ; elytra convex 

 cylindrical, with strong and strongly punctured striae ; under-side deeply 

 punctured, especially at sides ; the species may be known by its some- 

 what narrow head, and convex cylindrical elytra, which are evidently 

 more strongly striated and punctured than in the allied species. L. 3^- 

 4| mm. 



Under hark and at sap of freshly cut firs, &c. ; somewhat local, but widely dis- 

 tributed throughout England; Scotland, common, Solway, Tay, Dee, Moray, and pro- 

 bably other districts; Ireland, near Dublin ; it also occurs under bark of oak near the 

 burrows of Cossus lignijjerda.
